I am still trying to pick apart every little aspect on why our car slowed down! 2 years ago we ran brad penn 20w 50 oil which is partial synthetic and a napa gold filter. Last time out we ran 15w 40 rotella t oil with a cheapy fram filter. Between the 2 oils there wasn't a dramatic oil pressure change but there was a little. My question is has anyone tested the 2 oils and seen any et difference?
what did it run 2 yrs ago? What does it run now? What rpms, how are the springs?

I almost have to start a new post on picking apart our combination of parts between engine and suspension and see what everyone can come up with? Does anyone think this a good idea? Anyone for it!?
Yes post all your details in point form........ Sounds like you are trying to get 10 seconds worth of parts into the 11's and beating on it like it owes you 9's.............

The only thing to mine and everyone else who is trying to help disavantage is I only know what someone told me about the motor. I don't know what the true lift of the cam is and what the true compression is. I guess it's pretty safe to say I don't really no nothing that's in the motor for a fact. Like I said all I know is what someone told me. They also didn't tell us much either. Maybe I should wait untill I tear into the motor and put the leak down test on it and all that other stuff before I start running down through the combo because it wouldn't make a whole lot of sence anyway! So I guess as soon as I find out more deffient answers I will put pics and all the info up and we can go from there!
Before you tear into the motor on inspecting it check the total timing first, write that down Next look at each plug, keep them in order also so you can post some pictures of them on here. Last do the leak down and then the lift at the retainers with the .050 cam timing. BTW, to add onto your engine inspecting plate make sure and check both the intake and exhaust valve lift and timing, post the numbers so we can help you determine if the cam is in straight up, advanced or retarted

I do not think the gears had much to do with your loss of ET. Last year I had a 380 HP 360 crate motor in my D-50.Ran a best of 7.46 at 91 mph with 5.14 gears changed to 3.50 gears and ran a 7.60 at 90 mph.
